"I warmed up about five times," Bouchard joked about waiting out the previous match on Stadium Court. "I was happy to play well and keep my momentum."

Bouchard's first career match at Yale was almost as quick as her rise to one of the players in the WTA. She entered the week here as the No. 8 player in the world and off a final-round loss to Petra Kvitova at Wimbledon in June.

A GRINDER: Samantha Stosur had never played 5-foot-2 Kurumi Nara, but she had to work to beat her Monday afternoon on Stadium Court in a match that lasted two hours and 37 minutes. The Australian Stosur was able to prevail in three sets 7-6 (5) 6-7 (10) 6-2 to advance to a second round match with Bouchard.

"It was a very interesting match," Stosur said. "She got off to a great start and I wasn't doing what I wanted to at that point."

Stosur recovered after falling behind to take the first set, but gave it back in the second when Nara fought to force a third set.

"You lose it and you are like `gees,' it's a big disappointment," Stosur said. "But I was able to play well at the start of the third set and it gave me confidence."
